Hi Uwe,

Your documents are relatively small, so XEP can format them fast.
To increase performance you may turn off validation (-valid option, or
set "VALIDATE" property with the value of "false")and set maximum Java
heap size (-Xmx option) to a higher value.
If you are using XEP via API, it is important to reuse formatter
object instance for sequential formatting since its re-creation can
cause considerable overhead (doc/applications.pdf, "4. Notes on

You may also consider high performance solutions based on "formatting
server" called EnMasse (


>>we want to improve the performance of PDF creation with XEP.

>>We have documents of a size of ~20 pages containing ~10 TIFF graphics of ~30KB.
>>We run XEP on Windows 2000 Profesional Edition, ~4GB RAM and 2 x 3GHz CPU.

>>Which parameters we can set (validation, memory options, etc.) to improve performance?

>>Thank you very much in adavnce
